Feature Req: Add ability to configure /etc/docker/daemon.json from the GUI

Preflight Checklist

• I have searched the issue tracker for a feature request that matches the one I want to file, without success.

Problem Description

Docker Desktop has always given the ability to edit the docker daemon’s config from the GUI: (Image source: https://mandie.net/2017/12/10/docker-for-windows-behind-a-corporate-web-proxy-tips-and-tricks/)

(Image source: https://github.com/docker/for-win/issues/6633)

You can configure all kinds of useful settings in that file:

• registry mirroring
• insecure http registries
• configuring dns “dns”: [ “10.10.1.1”, “10.10.1.2”], “dns-serach”: [ “dev.local” ]
• https://docs.docker.com/engine/reference/commandline/dockerd/

Problem: Rancher Desktop Lacks the ability to easily update this file in the GUI

Proposed Solution

Add a new spot to the GUI to edit Docker daemon.json config file

Additional Information

I tried the following workaround, that didn’t work for me, but some could probably figure out if they spent a little more effort on.

# [user@Macbook bash/zsh:~]
brew install lima
export LIMA_HOME=~/Library/Application\ Support/rancher-desktop/lima
# Note the following commands, only work when the env var is set
limactl ls
limactl shell 0

# [user@LimaVM's bash:~]
sudo vi /etc/docker/daemon.json
sudo service docker restart
# Edit it didn't recover from that docker restart, so I just factory reset 
# Rancher-Desktop to fix it, and accepted the limitation for now. 
# (It could probably be debugged if someone needed the workaround)

[urld]

Maybe its sufficient to just make the config available as a mount point instead of a full GUI integration. In the case of WSL2, dockerd could be started, pointing to /mnt/c/Users/...../AppData/Local/rancher-desktop/etc/docker/daemon.json per default. Then I would not need to edit the config inside the wsl distro after every update and restart rancher-desktop afterwards.

this would be very helpful. our internal IP range clashes with the defaults so rancher desktop is unusable for a lot of things like this.
